Overview
Not yet reviewedProduct quality is assessed from original evidence. How reviews work.
Superhuman Mail is the email client within the broader Superhuman Platform (which also includes Docs and Go), engineered for professionals who process high email volumes and want the fastest possible email experience, every action is keyboard-driven, every interaction is optimized to reduce the time between opening the inbox and reaching zero unread messages. Its Split Inbox feature separates important email from newsletters and notifications automatically, so high-signal messages get attention first. Remind Me schedules email reminders for messages that need follow-up at a specific time rather than requiring inbox management mental overhead. The AI features include Instant Reply (one-click reply generation from context), AI Summary (condenses long email threads to the key points), and AI compose for drafting responses.
Read Receipts show when a recipient opened your email and on what device, providing follow-up timing intelligence for sales and business correspondence. Superhuman Mail works across Gmail and Outlook accounts. The cost is $30/month, the highest price point in the email client category by a significant margin, making it a deliberate choice for users who quantify their email time and can demonstrate ROI on the speed gains. Commonly used by executives, investors, and sales professionals who manage 100+ emails per day and treat email productivity as a direct lever on business output.

Our Take
Every action is keyboard-driven and the AI drafts hold up well, which together genuinely compress the time between opening the inbox and reaching zero unread. At $30 per month it is expensive relative to free clients, and signup is now fully self-serve via Google or Microsoft OAuth rather than invitation-gated. If email is not a daily bottleneck for you, the price is hard to justify. If it is, the speed difference is real enough that most users who try it do not go back.
